Abstract:
PROBLEM TO BE SOLVED: To reliably stop lifting/lowering operation, when being interfered with an obstruction during the lifting/lowering operation.SOLUTION: Furniture 1 with a top-board lifting/lowering function includes: a lifting/lowering unit 14 for telescopically moving in the vertical direction; a top board 15 supported on the lifting/lowering unit 14; a control device 20 for controlling the drive of telescopic motion of the lifting/lowering unit 14; and an angle detection part 21 and an angular speed detection part 22 for detecting an inclination state of at least one of the lifting/lowering unit 14 and the top board 15. During lifting/lowering operation for lifting or lowering the top board 15 by telescopically moving the lifting/lowering unit 14, when the inclination state detected by the angle detection part 21 and the angular speed detection part 22 exceeds a predetermined threshold, the control device 20 stops the lifting/lowering operation.SELECTED DRAWING: Figure 1
